The chapter focuses on the role and importance of trust in the processes of human resource management. In this chapter, the term "human resource management" refers to the strategic dimension of human management. Two relationships occur here: On the one hand, trust plays a huge role in the processes of recruitment, adaptation, training, motivation, and employee assessment. However, on the other hand, these processes may either enhance or destroy trust. Being one of the organizational values, trust cannot be maintained or developed when the levels of competence, fairness, and predictability of behavior are low. The chapter assumes that the development or loss of trust in an organization as an open system influences public trust - that is, both trust in an organization in its micro and macro environments and public trust related to employees' perceptions of their organization.
